Batteries for 3300

Nimh has been in production so long that prices are low, and the milliamp ratings can be very high if you want the reserve.
From what I recall NIMH & Nicad are both 1.2 volts
and stay at that voltage a very long time. Alkaline are 1.5 volts and once alkaline batteries discharge to 50% capacity, it's delivering a lower voltage than a rechargeable.
The problem with Nicads is they can develop a memory (at a certain point where a good charge remains--they stop discharging) and they have a tendency to reverse polarity too.
(Some units when switching from alkaline to rechargeables need more rechargeables to work--a ML Sovereign is this way.)
In the end NIMHs are a better deal than alkaline because they can be charged around 1000X. A good "smart charger" is inexpensive and will even work with alkalines (set them aside after
though to see if they leak. Also another variety, Rechargeable Alkalines (RAM) -- higher voltage + long shelf life. But have a short cycle life (can't be charged as many times as a real rechargeable) Capacity (and sometimes voltage) is reduced on every cycle. Doesn't work in high-drain devices
Do NOT recharge acid types like Hvy Duty as ever time I've tried they leaked. All rechargeables lose their charge over time through self-discharge even when not in a device. This can be up to 30% per month. So a battery is never fully charged when you go to use it , unless you keep it on constant trickle charge. Newer type NiMh batteries hold a charge for longer,( Low Self-Discharge) LSD. version; lithium-ion cells have very low self-discharge, ( and alkalines will store the charge a long time too.) and not available in standard voltage, except for 9V size (AAA, AA, C, and D-size Li-ion put out 3.7V instead of 1.5V.) You better have a voltage regulator or some circuits may be fried.
I cannot say that Nicad/NiMH will not leak, I've just never seen it happen. (Steer clear of some Chinese types because they seldom live up to advertising; batteries here have a guarantee that
if they leak they will repair or replace----foreign batteries may be a different proposition altogether.)
A newer type is NiZn (Nickel-Zinc) that has higher voltage (1.65V+); if you use a high drain device these might be good, but a voltage regulator may be necessary to protect electronics.
*** Whites does offer NiMH chargers.
